Abstract (English):
The subsystem for protection from static electricity of personnel wearing personal protective equipment (PPE) shall ensure safe operation of the technological line of disassembly and destruction (TL DD) in all its modes of operation, as well as to eliminate the possibility of an emergency situation due to the accumulation of static electricity charges on PPE during operation, to reduce the level of electrification on PPE, adversely affecting the technological process and product quality. The work on reduction of electrification of insulating material UNKL-3 of L-1 suit for special works was carried out. Literature review of existing technical solutions for protection against static electricity accumulation on the surface of polymers used in chemical industries was carried out. On the basis of literature data and conducted experiments an effective surface-active substance, antistatic agent Alkapav was chosen. It is well sorbed by polymeric materials on the basis of butyl rubber, so it is evenly distributed on the surface of the L-1 suit. Physical and mechanical parameters of UNKL-3 material after treatment with Alkapav antistatic agent remain unchanged. The results of the conducted research allow us to consider that the materials of L-1 suits after treatment with 10% aqueous solution of the selected antistatic agent Alkapav and subsequent operational tests do not exceed the value of specific surface electrical resistance (SSER) 1,0-109 Ohm, i.e. the indicators meet the requirements of GOST 12.4.124-83.
